摘要

Preexisting micropores and microcracks within solid cement paste cause a variation in both the cell wall modulus of rupture and fracture toughness of foamed cements. Here, we determine for the variability of cell wall modulus of rupture by assuming that it follows a Weibull statistical distribution. Consequently, the variation of fracture toughness of foamed cements depends on the Weibull modulus of solid cement paste. A series of measurements on the Mode I fracture toughness of foamed alumina cements with various relative densities were conducted. Results indicate that the Weibull moduli of solid cement paste for foamed alumina cements are within the range of 7 to 10 except for the foamed alumina cement with a relative density of 0.167.
